Dear Giacomo.
Thank you for your kind reply.
And, I will take care to keep the list in CC.
I changed parentheses to curly braces as :
axis {1, 0, 0} → axis (1, 0, 0)
Then, following error message were output :

Are there 2 problems ?
In previous exchange for others, I obtained following manual page
http://colvars.github.io/colvars-refman-namd/colvars-refman-namd.html#x1-530005.3.3
But, I cloudn't resolve above problem
Thanks.

Hello Takeru, please keep the list in CC.
Your error is due to using curly braces instead of parentheses.

Dear Giacomo
Thank you for your kind reply.
I tried ABF as you said using attached files.
However, I obtained attached log file (run.log).
Are there any missing configurauin ?
Thanks

Hello Takeru, it looks like you already found the documentation, try to double-check that your configuration is consistent. See here an example:
If it is consistent with the doc, do you mind pasting it in the email or attaching it?

Thank you for your advice.
I changed the method orientation to spinAngle.
Now I'm trying such method.
In this case, I think I must set the axis of rotation and center of roration.
Do you know how to set such axis and center.
Best wishes,

Dear Takeru,
this "failed dependency" message indicates that ABF only supports scalar variables. A multidimensional ABF calculation can be done with several scalar variables, not a single vector one.
In this case, the orientation variable is 4-dimensional, which is probably too much for ABF anyway. I recommend reducing your sampling space to 1, 2 or 3 scalar quantities.
Best wishes,

Hi. I am trying multi-canonical ensemble method using NAMD2.13.
I wrote colvar file as follows:

Any parts of configulation file was wrong?
